【摘要】 针对金属矿山目前局部通风存在的突出问题，设计了一种应用ABS刚性轻质高强度小断面风筒配合小型鼓风机的局部通风降温装置及其应用参数，通过与其它现有局部通风降温方法进行技术经济比较和试验表明，该新方法经济实用，具有广泛的推广应用价值。更多还原

【Abstract】 To solve the key existent problems of ventilation in dead face in China’s metal mines currently,a new ventilation and temperature drop facility, which consists of a light, strong and stiff ventilation pipe ofABS with small diameter and a small blast fan, was designed for improving the environmental quality in deadface of excavation. As compared with other existing local ventilation and temperature drop methods both econornically and technologically, the facility was shown that it is more effective and energy saving, especially forthe dead face and blind raise with small cross sectional area.更多还原
